In emergency fire situations in road tunnels in which vehicles cannot exit the tunnel, evacuation on foot might be the only alternative. In such scenarios, self-rescue using rescue rooms might provide provisional safe shelter to people trapped in tunnel emergencies. Yet, a stay in a rescue room with unsatisfactory design might contribute to higher levels of distress to the users. The present study examines five different designs of rescue rooms via virtual reality, to study how the different design and spatial factors might affect users' acceptance of such rooms. Thirty-seven people participated in the study, in which both objective (Eye-tracking and heart rate measurement) and subjective data was collected. The results suggest that two factors (i.e. lighting and use of separate areas) increased the feelings of safety and users' acceptance of the rescue rooms. In particular, a container room with blue lighting and separate area for injured people was the favourite among the study participants. The outcomes of this study show that design and spatial factors are crucial if rescue rooms are to be implemented and used in road tunnels.
